TofaZZ wito'm it may concern I Be it"kn'own that I, J os'HUA BQHALn', a

citizen of theUnited'States, and a resident of Providence in-the county of Providence and State of Rhode Island, have invented an Improvement in Braiding-Machine Can riers, of whichthe followingdescription,in connection with the accomp anying drawings, is a specification, like characters on the drawings representinglike parts This invention, relates to braiding machine carriers and'particularly to braiding machinecarriers having resilient bodies.

In order that the principle oi theinvention may be readily understood, Ihave dis; T closed a single embodiment of my invention, wherein- 5'1 F g. 1 is atop plan'view'; Fig. '21s a side elevation;-

3' isa vertical section on the line 3-3 of'Fig. 2;and F e-V e I Fig. 4; is a plan view with parts broken away, showing so much of a braiding ma chine as its-necessary to illustrate the 11110" tioning of my improved braiding carrier and the advantagesthereof lIkOPBIfltlOIL- Braid ng machine carriers or members,

In my co-pending applicationSerial No. 356,363, I have represented proved form and to whichpmy present in vention may be applied though obviously this invention is not limited in fitsapplication thereto but s of broad application 'A braiding carrier is provided -with a- I bodyportion whereon'the yarn supply is carried and a bearingor guidingsurface;

So far as lam aware, I am the first to provide acarrier with an inner preferably rigid body or shank having a yielding or resilient. bearing surface.

Obviously other'tor nations may be employed Within the scope and purpose of my invention but in that form herein disclosed the resilient inembers'or plates 3, a may be taken'ofi' from the shank or body portion ot the carrier and be replaced it worn at low cost-compared with the replacement of the I entire carrier.

Viewing Fig. 2, it Will be evident that the bearing or guiding portion of the carrier is CQIHPOSClOf3-Il upper portion a and a'lower portion'b united by a web a, the parts a, b and c of each plate 3, a beingan integral structure. Thus the'rn'enibers a o are not strictly bifurcated but are connected at their I extremities'by the web 0, thereby more accurately locating and positioning the parts of the said plates andin such a manner as to givegreater strength and endurance. Obviously my invention is not limited. to a bifurcated structure of braiding carrier bearing or guiding member which is herein merely-shown for purposes of illustration since my invention is of broad application and is intended to-be used in any relation.

- Therein l have indicated tour braiding carriers oryparts thereof. it will be clearly evident that each of said carriers together with its load and its ovenworks must be re v versedin direction because of the 1n1p111i5- rnent of said carriers against aiwall of the .;raceway in whi'chgit is traveling-1" For 1-:- ample, the carrier A moving t'rom the point A in the-direction of the arrow adjacentthereto and in a general" clockwise direction 'w llimpact against the mass cfthe body This impact is f very consider:
